Wikipedia reckon that there are three ‘poles of cold‘ in the world, two in the northern hemisphere in the Sakha in eastern Russia at Verkhoyansk and Oymyakon, and the other and by far the coldest in the southern hemisphere in Antarctica at the Vostok Station. I have spent some time improving the thermographs in my SYNOP temperature application during the last week and decided to give at a trial run by collecting the data and plotting the graphs for these three SYNOP stations. Because of the different time zones you have to trawl through around 1,600 three hourly data files to generate these graphs but I’m pleased with the results I have produced after a lot of fiddly tweaking, and I seem to have extracted the maximum from the Delphi graphing component that I use. Interestingly all three cold poles stations are all a long way east of the meridian, perhaps this has to do with the their position relative to the massive Pacific Ocean?
This years extrem warming of the Arctic is easy to see in the Verkhoyansk plot, but not quite as pronounced in the one from Oymyakon much further southeast. As a rule of thumb I have come to realise that to make a heatwave mean anomalies have to be 10°C or higher. You’ll notice that at Verkhoyansk the highest anomalies were in the spring, rather than when they hit the headlines during the summer with the 100°F, and to be honest the first half of 2020 looks slightly less warm than it did in 2019.
Meanwhile the big daddy of the three cold poles, Vostok Station, has had a very cold autumn (during March), but since then temperatures have become relatively warm for that part of Antarctica, with mean temperatures as high as 20°C above average.
All the daily anomalies that I calculate in this application are rather crude approximations because I only have the monthly mean LTA to play with. That monthly LTA data is available to download from the UKMO and is what they use to calculate their global temperature series with. What I would like to do is add the monthly maximum and minimum temperatures for selected stations, which I can copy from Wikipedia. That will improve the look of the top graph slightly.
